Motorola is getting ready to hook Verizon up with another LTE-capable smartphone, at least according to the company’s latest FCC filing. The documents tell the tale of a handset equipped to run on Verizon’s LTE band 13, but just what model are we looking at? A couple phones come to mind as possibilities, but it seems like this time we’re dealing with the Motorola Droid 4.

There are other Motorola models we expect to eventually show up on Verizon LTE, like the RAZRMAX we uncovered last week. From the sound of it, though, that model would end up slightly larger than the Droid RAZR we have now, and these FCC documents describe a phone that is ever-so-slightly smaller than the RAZR.

While Motorola’s always quite careful not to let too much information about its phones slip-out in these FCC filings, it couldn’t help but reveal the results of multiple tests done to show the effect of emissions with the keyboard both open and closed. The Droid 4 is the only QWERTY slider we’re expecting for Verizon LTE in the near future, so it’s very likely that’s the handset in question.

With that out of the way, the Droid 4 should be nearly ready to go. We were expecting the phone to arrive in early December, but a more recent rumor says we might be waiting until December 22.
